Re: no sound when on pc mode

Check if your PC can play audio on some other speakers or headphone. If yes, check your monitor audio cable connections. If no something's wrong with your PC audio drivers. Try re-installing them or could be a hardware issue with your PC. Get it checked.

Have sound but no tv picture

That model used the same power supply that the Samsung 940mw uses and when the capacitors go out you get sound but no picture just like you are getting. The repair is easy, you just need to replace the bad capacitors on the power supply board. Here is a link to the repair guide for the 940mw that should help you get your 910 back going, same power supply so the same repair.

I hope this helps.

That is a hell know problem with the 940MW tv/monitors. The power supply has failed because of parts called capacitors have shorted. If you can solder then you should be able to repair your monitor. Here is a link to the repair guide for this issue.

It turns off automatically and then I cant get it back on.

maurice_camp Read the post I did for other Samsung 940MW's by clicking on the name "SyncMaster" above. You too probably have a "switch-mode-power-supply" that has gone into shutdown mode because it has detected a fault with some other circuit or even itself.

I wasn't able to find a 940MW. I do see a 941MW and a 940NW.
The 941MW manual has some basic instructions on page 36.

The 940NW manual can be found here.

Good luck!
